Ability to categorize end-feel joint movement according to years of clinical experience: an experiment with an end-feel simulator.

[Purpose] Discrimination between end-feel types is difficult, and years of clinical experience is considered a factor for improving the accuracy of the discrimination. The present study investigated whether the accuracy of classification of end-feel types improves with the increase in years of clinical experience. [Participants and Methods] In total, 44 therapists (range of years of clinical experience: 1-26 years) and 13 students were included.

Gait oscillation analysis during gait and stair-stepping in elder patients with knee osteoarthritis.

Background: Evaluation of knee and lower limb function alone is not sufficient to assess gait. For accurate assessment of gait abnormality, gait oscillation should also be measured. The goal of this analysis was to assess the influence of the knee joint on gait oscillation during gait and stair-stepping in patients with osteoarthritis of the knee.

Knee Arthritis Without Other Joint Symptoms in the Elderly With Seronegative Elderly Onset Rheumatoid Arthritis.

Elderly onset Rheumatoid arthritis (EORA) has important clinical distinctions when compared with younger onset RA (YORA). In knee arthritis of elderly patients, infection, crystal-induced arthritis or EORA should be suspected if elevation of CRP in the preoperative examination and turbid joint effusion in their knee joint are found. Furthermore, if joint swelling and effusion remain after performing total knee arthroplasty (TKA), the infection after TKA, implant debris-related arthritis and EORA should be considered.

Kinematic analysis of posterior-stabilized total knee arthroplasty during standing up from and sitting down on a chair.

Background: Total knee arthroplasty is effective to regain quality of life. Standing up from and sitting down on a chair and stair stepping motion are important in daily living. We previously reported in vivo kinematics of this implant during a stepping exercise.

The Role of Complete Suprapatellar Plicae.

Shelf syndrome mainly affects younger people, often athletes. Cases of complete suprapatellar plica syndrome are rare. Arthroscopic inspection is necessary to diagnose complete suprapatellar plicae.

In vivo kinematics of a unique posterior-stabilized knee implant during a stepping exercise.

Background: Stair-stepping motion is important in daily living, similar to gait. Knee prostheses need to have even more superior performance and stability in stair-stepping motion than in gait. The purpose of this analysis was to estimate in vivo knee motion in stair stepping and determine if this unique knee prosthesis function as designed.

Gait parameters in women with bilateral osteoarthritis after unilateral versus sequential bilateral total knee arthroplasty.

Purpose: To compare gait parameters in women after unilateral total knee arthroplasty (TKA) versus sequential bilateral TKA to determine the need for sequential TKA.

Methods: 35 women aged 60 to 74 (mean, 70) years with bilateral varus knee osteoarthritis (OA) underwent unilateral (n=23) or sequential bilateral (n=12) TKA by a single surgeon. All patients underwent unilateral TKA; 12 patients then underwent sequential TKA after 3 to 6 months of the first TKA.

Unusual appearance of an osteochondral lesion accompanying medial meniscus injury.

An osteochondral lesion in the knee joint is caused by a focal traumatic osteochondral defect, osteochondritis dissecans, an isolated degenerative lesion, or diffuse degenerative disease. An osteochondral lesion with a cleft-like appearance accompanying medial meniscus injury is rare without trauma. We report the case of a 13-year-old boy who complained of right knee pain and swelling, with radiographic findings of an osteochondral defect.

Collagen expression in various degenerative meniscal changes: an immunohistological study.

PURPOSE. To examine changes in acid mucopolysaccharides and collagen expression during meniscal degeneration, tearing, and repair, using menisci excised from knee joint surgeries. METHODS.

Shelf syndrome of the knee in elderly people: a report of three cases.

Shelf syndrome occurs mainly in younger people (particularly athletes) and rarely in elderly people. We report on 3 elderly patients with a medial synovial plica causing severe pain and locked knees. They had had no symptoms in their early or middle life.

Intra-articular synovial cyst of the knee joint: a case report.

Synovial cysts occur secondary to injury, mucinous degeneration or tumours. We report a patient with snapping of the knee joint caused by a synovial cyst located near the patellofemoral joint which developed as a result of minor trauma.

Effects of rice proteins from two cultivars, Koshihikari and Shunyo, on cholesterol and triglyceride metabolism in growing and adult rats.

The effect and mechanism of two types of rice protein, one from regular japonica rice Koshihikari and another from rice cultivar Shunyo, with low glutelin and high prolamin content, on cholesterol and triglyceride metabolism were compared by feeding casein and soy protein to male Wistar strain rats 7 and 20 weeks old ad libitum for 2 weeks. The results in adult rats clearly indicated that both rice proteins had cholesterol-lowering effects in the plasma and the liver, comparable to soy protein, and the effects were accompanied with TG-lowering effects in the liver. Similar effects were also observed in growing rats when the diets were supplemented with cholesterol.

Production of rice protein by alkaline extraction improves its digestibility.

Rice seed endosperm has two types of protein bodies (PB). Type I protein body (PB-I) accumulates prolamin and is hard to digest, while type II protein body (PB-II) mainly consists of glutelin, an easily digestible protein. A simple method to process rice protein and improve its digestibility was tested from the viewpoint of its application to food manufacturing.

Reduced immunogenicity of beta-lactoglobulin by conjugation with acidic oligosaccharides.

Bovine beta-lactoglobulin (beta-LG) was conjugated with the acidic oligosaccharides, alginic acid oligosaccharide (ALGO) and phosphoryl oligosaccharides (POs) by the Maillard reaction to reduce the immunogenicity of beta-LG. The molar ratios of beta-LG to ALGO and POs in the conjugates were 1:6 and 1:8. The carbohydrate-binding sites in the beta-LG-ALGO conjugate were partially identified to be (60)Lys, (77)Lys, (100)Lys, (138)Lys, and (141)Lys.
